Correct Answer - Option 2 : 384
Given:
The volume of a cube is 512 cm3
Formula Used:
Volume of cube = Side3
Total surface area = 6 × Side2
Calculation:
The volume of a cube is 512 cm3.
Let the side be x.
⇒ x3 = 512
⇒ x = 8 cm
Total surface area = 6 × 82 = 384 cm2
∴ The total surface area is 384 cm2.
